SCOPEThe information described in this section is for airplane models 737-600/700/700C/800/900/900ER and all derivatives.The scheduled maintenance requirements described in this section result from all 737-600/700/700C/800/900/900ER and derivativeairplane certificationactivities with the U.S. Federal Aviation Administration (FAA).Accordingly, this FAA approvedAirworthiness Limitations (AWLs) and CertificationMaintenance Requirements (CMRs) document is cross-referenced in the Model 737 Type Certificate Data Sheet, A16WE. This document satisfies therequirements of United States Code of Federal Regulations (CFR) Title 14, 25.571 and 25.1529 and Advisory Circular (AC) 25-19 as the controllingdocument for all 737-600/700/700C/800/900/900ER AWLs and CMRs. These maintenance actions are mandatory.The Airworthiness Limitations Section is FAA approved and specifies maintenance required under Federal Aviation Regulation CFRTitle 14, 43.16 and91.403 unless an alternative program has been FAA approved.AIRWORTHINESS LIMITATIONS (AWLs)The Airworthiness Limitations (Structural Inspections and Safe LifeLimitations) may only be revised with the approval of the Seattle FAA ACO.If the inspections cannot be accomplished due to repairs and/or modifications, an alternate inspection must be approved by theSeattle FAA ACO.B. AWLs– STRUCTURALINSPECTIONSINTRODUCTIONThe scheduled maintenance requirements described in this section are applicable to all 737-600/700/700C/800/900/900ER airplanemodels and allderivatives. This section is also applicable to 737-700/700C/800/900ER aircraft that have winglets installed in the factory asidentified in Table 9-1.JUN 2011D626A001-CMRBOEING PROPRIETARY - Copyright (c) - Unpublished Work - See title page for details Page 9.0-40737-600/700/700C/800/900/900ER MAINTENANCE PLANNING DATAThe 737-600/700/800/900 Maintenance Review Board (MRB) Report outlines the initial minimum scheduled maintenance/inspection requirements(hereafter referred to asthe baseline program) for all structure, including all Principal StructuralElements (PSEs). This baseline program was developedin accordance with the guidelines of MSG-3 and satisfies requirements of CFR Title 14, 25.571 and 25.1529 by providing accidental, environmental, andfatigue damage detection opportunity for all PSEs. In order tofully comply with therequirements of CFRTitle 14, 25.571 thesupplemental structuralinspections defined herein, are required to be accomplished prior to the stated threshold. These supplemental inspections conducted in conjunction withthe baseline program found in the MRBR satisfy the certification requirements of CFR Title 14, 25.571 and 25.1529.The baseline program defines the inspection task as one that includes accomplishment of the CPCPBasic Task at all initial andrepeat inspections unlessnoted otherwise. It is a requirement of this section that all structure identified in Section 3 ofthe 737-600/700/800/900 MRBReport be maintained with theuse of a Corrosion Prevention and Control Program. The objective of the CPCP is to control corrosion to Level 1 or better.TABLE 9-1 737 MODELS WITH PRODUCTION INSTALLED WINGLETS COVERED BY THIS DOCUMENTaMODELLINE NUMBERSWINGWINGLET737-700b1545 and onYesNo737-700IGW3128 and onYesYes737-700C3346 and onYesYes737-800778 and onYesYes737-900ERAllYesYesa.

The baseline program defined in the MRB Report is intendedto serve as a guideline forestablishing initial inspection requirements for new operators’ maintenance programs. Initial adjustments may be necessary toaddress operational and/orenvironmental conditions unique to the operator. As operatingexperience is accumulated, additional adjustments may be made bythe operator withFAA Principal Maintenance Inspector (PMI) approval in accordance with CFR Title 14, Part 121 in order to maintain an efficient and effective maintenanceprogram.The fuselage and empennage structure of the 737-600/700/700IGW/800is not significantly modifiedfrom the 737-300/400/500 and is certified to CFR Title14, 25.571, Amendment 0. Although a damage tolerance analysis isnot required for certification of the fuselage and empennage,AC 91-56 does requirethat a supplemental structural inspection program (based on a damage tolerance assessment) be developed for structure certifiedto the early versions ofCFR Title 14, 25.571. The 737-700C and 737-900/900ERare certified to CFR Title 14, 25.571, Amendment 86.THRESHOLDTable 9-2 of this section defines the supplemental inspection implementation threshold. Each item is listed by PSE Number, DTRCheck Form Title,Location, Inspection Zone, Airplane Applicability, and Threshold.

At the timeof initial certification of thisproduction change, the Airworthiness Limitations for the horizontalstabilizer have been established by requiring a conservative inspection thresholdon an initial list of PSEs.For all model 737-700C airplanes, Line Number 3346 and on, and all model 737-700IGW airplanes, Line Number 3128 and on: For those airplanesequipped with winglets as an original factory installation, atthe time of initial certification of the winglets, the Airworthiness Limitations for the horizontalstabilizer have been established by requiring a conservative inspection thresholdon an initial list of PSEs.The inspection threshold for the subject PSEs on the affected737-600/700/700C/800/900ER and 737-700IGW airplanes described above is 10,000 flightcycles or 20,000 flight hours, whichever occurs first. Operators are instructed to contact Boeing for FAA approved inspectionswhen airplanes reach theinspection threshold.The initial supplemental inspections must beaccomplished prior to the cycle and/or hour threshold listed (prior to the first occurring). Some items aresensitive to flight length and are identified by FLS (Flight Length Sensitive) in theThreshold column of the table. FLS itemsrequire both flight hours andflight cycles to determine the implementation threshold. Refer to Figures 9-1 and 9-2 (as directed by Table 9-2 for a given PSE) to determine the thresholdfor FLS items.Instructions for the use of FLS Threshold Curve:1. Determine, for each airplane, the accumulated flight cycles and flight hours.2. Enter the FLS threshold curve at the appropriateflight cycles and flight hours and plot point.3. The initial supplemental inspection must be accomplished before crossing into the shaded area on the FLS threshold curve.Initial inspection (threshold) and intervals are measured in flight cycles or flight hours thata particular PSE detail has accumulated regardless of what theairframe as a whole has accumulated. Most PSE details have never been replaced and therefore haveaccumulated the same flightcycles and flight hoursas the airframe. Some PSE details are replaced, such as wheninstalling RemovableStructural Components(repairable/rotable/expendables) or installingused structural parts as a repair. In these cases the PSE details have accumulated flight cycles and flight hours that may bedifferent than the airframe.The operator must account for this in determining when inspectionsmust be done. In determining the PSE flight cycles or flight hours, operators may useprocesses defined in AC 120-93.OCT 2011737-600/700/700C/800/900/900ER MAINTENANCE PLANNING DATAD626A001-CMRBOEING PROPRIETARY - Copyright (c) - Unpublished Work - See title page for details Page 9.0-43FIGURE 9-1.

The DTR system defines a required DTR (a numerical value) that must beachieved for eachPSE. DTR Check Forms, which define the inspection options andthe required DTR are contained in D626A001-DTR.All PSEs that met the DTR requirement through the baseline programhave been evaluated for up to25% escalation of the baselineinspection flight cycleintervals. The additional supplemental inspections as a result of the escalation tothe baseline program are identified with Note <1> in Table 9-2. Thesenoted supplemental inspections must be accomplished prior to the given threshold if the baseline program is escalated by any amount. The 36,000 cycleinterval was not considered for escalation and is the maximum interval allowed for supplemental inspections. Where credit forthe baseline StructuresProgram is taken on a DTR Check Form, the DTR Check Form must be reevaluated and adjusted by the operator (to maintain total DTR equal to orgreater than the required DTR) upon any escalation of the baseline program. If the baseline program flight cycles are escalated beyond 25%, contact theSeattle FAA ACO.A repeat inspection interval for the fatigue inspection of a PSEis established from its DTR Check Form. Revision to the required DTR or the DTR curve isnot allowed without approval from the Seattle FAA ACO.Some structures and zonal MPD items have been escalated by theIndustry Steering Committee beyondthe initial repeat interval considered at the time ofthe initial aircraft certification. The intervals listed in Appendix J correspond to the original task intervals used in determining the DTR which satisfies 14CFR Part 25.571. As a result, prior to or at the threshold specified in Table 9-2, the items listed in Appendix J are requiredto be returned to the interval inthat appendix, rather than what is listed in Sections 2 and 3 of this MPD.OCT 2011D626A001-CMRBOEING PROPRIETARY - Copyright (c) - Unpublished Work - See title page for details Page 9.0-46737-600/700/700C/800/900/900ER MAINTENANCE PLANNING DATASPECIAL STRUCTURAL INSPECTIONSThe following special inspections are required forhorizontal stabilizer front spar attachment bolts and rear spar attachment pins.

These aircraft may be modified with Service Bulletin (SB) 737-21-1149that increases themaximum operating cabin pressure from 8.35 psi to 8.99 psi.Operators of BBJ airplanes that have incorporated SB 737-21-1149,in addition to the all previously cited structural inspections, also require thesupplemental inspections identified in Table 9-3 of this section. These limitationsare permanent for the service life of theairplane, regardless of asubsequent reversion to any lower internal cabin pressure, or removal of SB 737-21-1149, and can only be changed by a completeengineering analysisapproved by the manager of the FAA Los Angeles Aircraft Certification Office (ACO).It has been discovered that production sealant application has exceeded specification limits in some locations and the damage tolerance analysis onlyaccounts for the specification maximum amount of sealant. The amount of sealant affects how much of the PSE structure is hidden for visual inspections.Excessive sealant (beyondspecification limits) on PSEstructure could affect the damage tolerance analysis results.

AWLs– FUEL SYSTEMSINTRODUCTIONThe airplane systems maintenancerequirements described in thissection of the AWL document result from various 737 airplane certification activities withthe FAA. These maintenance requirements are required under the Code of Federal Regulations (CFR) 43.16 and 91.403. The AWLs may only be revisedwith the approval of the Seattle FAA Aircraft Certification Office (ACO). If the maintenance requirements cannot be accomplished due to repairs and/ormodifications, an alternate inspection, acceptable to the Seattle FAA ACO, must be used.An AWL may be an Airworthiness Limitation Instruction (ALI) or aCritical Design Configuration Control Limitation (CDCCL).CDCCLs are a means of identifying certain design configuration features intended to preclude a fuel tank ignition source for the operational life of theairplane. CDCCLs are mandatory and cannot be changed or deleted without the approval of the Seattle FAA ACO that is responsiblefor the airplanemodel Type Certificate, or applicable regulatory agency. A critical fuel tank ignition source prevention feature may exist in the fuel system and its relatedinstallation or in systems that, if a failure condition were to develop,could interact with the fuelsystem in such a way thatan unsafe condition woulddevelop without this limitation. Strict adherence to configuration, methods, techniques, and practices as prescribed is required to ensure compliance withthe CDCCL. Any use of parts, methods, techniques or practices not contained in the applicable CDCCL mustbe approved by the Seattle FAA ACO that isresponsible for the airplanemodel Type Certificate, or applicable regulatory agency. For each CDCCL, the word "maintenance" includes maintaining anyinstallation during alterations; therefore, adherence to the CDCCL is required during maintenance or alterations.ALIs identify inspection tasks related tofuel tank ignition source prevention which must be done to maintain the design levelof safety for the operationallife of the airplane. These ALIs are mandatory and cannot be changed or deleted without the approval of the Seattle FAA ACO that is responsible for theairplane model Type Certificate, or applicable regulatory agency. Strict adherence to methods, techniques and practices as prescribed is required toensure the ALI is complied with. Any use ofmethods, techniques or practices not contained in these ALIs must be approved by the Seattle FAA ACO thatis responsible for the airplane model Type Certificate, or applicable regulatory agency.MAR 2011737-600/700/700C/800/900/900ER MAINTENANCE PLANNING DATAD626A001-CMRBOEING PROPRIETARY - Copyright (c) - Unpublished Work - See title page for details Page 9.0-119USE OF ALTERNATE TOOLSThe Component Maintenance Manuals (CMM) listed in the AWLs are currently Seattle FAA ACO approved.If the CMM allows the use ofalternate orequivalent tools, test equipment or materials, use of an alternate or equivalent tool, test equipment or material does not require further approval by theSeattle FAA ACO or local Regulatory Agency. For inside of the tank, use sealant type BMS 5-45 or equivalent per SRM 51-20-05.For outside of the tank,use sealant type BMS 5-95 or equivalent per SRM 51-20-05.EXCEPTIONAL SHORT-TERM EXTENSIONSSince AWL intervals are based on estimations of the probability ofan event, an exceptional short-term extension for each fuelsystem AWL listed in thisdocument may be made without jeopardizing safety. The local regulatory authority (e.g. a Principle Maintenance Inspector) mustconcur with anyexceptional short-term extensions before they take place using procedures established with the local regulatory authority in the operators’ manuals. The“exceptional short-term extension” process is applicable to AWL intervals. It should not be confused with the operator’s short-term escalation” program fornormal maintenance tasks described in the operators’ manuals and in the Flight Standards Handbook 8900.1 FSIMS.The Seattle FAA ACO has accepted that these exceptional short-term extensions may be granted without consultation with that office:1. The term “exceptional short-term extension” is defined as an increase in a System AWL interval that may be needed to cover anuncontrollable orunexpected situation. All AWLs listed in this section have been approved with an exceptional short-term extension of 30 days.2. Repeated use of extensions, either on the same airplane or on similar airplanes in an operator’s fleet, should not be used asa substitute for goodmanagement practices. Exceptionalshort-term extensions must not beused for fleet AWL extensions.After a fuel system AWL has experienced an exceptional short-term extension, the AWL interval will revert back to its intervallisted in this document. TheSeattle FAA ACO must approve, prior to its use,any desired extension notexplicitly listed above.This exceptional short term extension listed above applies to airlines that fall under the UnitedStates FAA jurisdiction only.Operators who are not underthe U.S. FAA jurisdiction should obtain interval extension approvals from their local regulatory agency.FEB 2011D626A001-CMRBOEING PROPRIETARY - Copyright (c) - Unpublished Work - See title page for details Page 9.0-120737-600/700/700C/800/900/900ER MAINTENANCE PLANNING DATAREGULATORY AGENCY APPROVALAny deviations from the published AWL instructions included in this document require approval from the Seattle FAA ACO. This applies to operatorsunder the US FAA jurisdiction only and to airplanes registered in the US.

Theflammability exposure is also affected by the temperature of the fuel. The following are criticalfeatures of the airplane that, if altered, can negatively affect the performanceof the NGS which in turnmay increase the center fuel tank flammability exposure beyond the limits of 14 Code of FederalRegulations, Section 25.981 at Amendment 25-125, utilizing the equivalent level of safety findingdescribed in FAA Memorandum PS05-0177-P-2.1. Transferring air (20.9% oxygen) to the center fuel tank will dilute the nitrogen richatmosphere created by the NGS inthe fuel tank. Some Auxiliary Fuel Tank installationstransfer air to the center wing tank aspart of venting and fuel transfer.2. NGS performance depends on bleed air pressure in the bleed air cross-over manifold suppliedby the engines.3. Certification of the NGS depends on the inherentflammability of the center fuel tank withoutNGS installed. Center tank flammability is a direct function of fuel tanktemperature. Any heatsources around the tank, heat sources introducedinto the tank (such as warm fuel or newheat exchangers), or changes that would causeheat to be retained (such installation ofblankets adjacent to tank walls) could affectfuel tank flammability in a negative manner.CDCCL: Any design change that affects the vent systemby adding air to the center tank, reduces thebleed pressure in the cross-over manifold duringany phase of flight orground operations, or addsany heat to the center wing fuel tank or increasesheat retention of the center wing fuel tank is notallowed without an FAA approved analysis to showthat the change, or combination of changes, doesnot affect the NGS performance per the requirements of 14 CFR Section 25.981(b), Amendment 25-125 utilizing the equivalent level of safety finding described in FAA Memorandum PS05-0177-P-2See Boeing AMM Chapter 28 for a description of the Fuel System.

CERTIFICATION MAINTENANCE REQUIREMENTS (CMRs)SELECTION OF CMRsIn order to grant operators of the 737-600/700/700C/800/900/900ER airplanean opportunity to participate in the evaluation andselection of CMRs in anintegrated process with MRBR tasksand intervals, a CertificationMaintenance Coordination Committee (CMCC) was convened to review all of the737-600/700/700C/800/900/900ER CMRs. The CMRs listed in this document are the result of applying the CMCC process as describedin AC 25-19.CMR DEFINITIONAs defined by AC 25-19, a CMR is a required periodic task, established during the design certification of the airplane as an operating limitation of the typecertificate. CMRs usually result froma formal, numerical analysis conducted to show compliance with catastrophic and hazardous failure conditions.Additional notes concerning the definition of CMRs:1. A CMR is intended to detect safety-significant latent (hidden) failures that would, in combination with one or more specificfailures or events, result in ahazardous or catastrophic failure condition.2. It is important to note that CMRs are derived from a fundamentally different analysis process than the maintenance tasks andintervals thatresult fromthe Maintenance Steering Group (MSG-3) analysis associated with Maintenance Review Board (MRB) activities. MSG-3 Analysis activity producesmaintenance tasks that are performed for safety, operational, or economic reasons, involving both preventative maintenance tasks, which areperformed before failure occurs (and are intended to prevent failures), as well as failure-findingtasks. CMRs, on the other hand, are failure-findingtasks only, and exist solely to limit the exposure to otherwisehidden failures. Although CMR tasks are failure-finding tasks,use of potential failurefinding tasks, such as functional checks and inspections, may also be appropriate.3. CMRs are designed to verify that a certain failure has or has not occurred, anddo notprovide any preventative maintenance function. CMRs “restartthe failure clock to zero” for latent failures by verifying that the item has not failed, or cause repair if it has failed. Because the exposure time to a latentfailure is a key element in the calculationsused in a safety analysis performed toshow compliance withCFR Title 14, limitingthe exposure time willhave a significant effect on the resultant overall failure probability ofthe system. The CMR taskinterval should be designated in terms of flight hours,cycles, or calendar time, as appropriate.JUN 2011737-600/700/700C/800/900/900ER MAINTENANCE PLANNING DATAD626A001-CMRBOEING PROPRIETARY - Copyright (c) - Unpublished Work - See title page for details Page 9.0-1474. The type certification processassumes that the airplane will bemaintained in a condition ofairworthiness at least equal toits certified or properly alteredcondition. The process described in AC 25-19 is not intended to establish normal maintenance tasks that should be defined through the MSG-3analysis process. Also, this process is not intended to establish CMRs for the purpose of providing supplemental margins of safety for concerns arisinglate in the type design approval process.5. CMRs should not be confused with required structural inspection programs that are developedby the type certificate applicantto meet the inspectionrequirements for damage tolerance, as required by CFR Title 14,Appendix H25.4 (Airworthiness Limitations section). CMRs are to be developed andadministered separately from any structural inspection programs.CMR TYPESCMR tasks are divided into two categories: One Star CMRs(*) and Two Star CMRs (**). They are defined as follows:1. One Star CMRs (*) – The tasks and intervals specified are mandatory and cannot be changed, escalated, or deleted without the concurrence of theSeattle FAA ACO.2. Two Star CMRs (**) – Task intervals maybe adjusted in accordance with each operator’s approved escalation program or an approved reliabilityprogram in a like manner for any MRB Report task, but may not be deleted without prior Seattle FAA ACO approval.ESCALATION OF TWO STAR CMRs (**)All Two Star CMRs (**) can be managed and controlled the same asany MRB Report task; however, they can not be deleted from anoperator’s programwithout prior Seattle FAA ACO approval. For operators with approved escalation practices oran approved reliability program, data collection andanalytical techniques are used to make adjustments to an operator’s maintenance program. It has been demonstrated that the management of amaintenance program does not give rise to undue escalations; consequently, the escalation of Two Star CMR (**) intervals withinan operator’smaintenance program will be properly managed by the operator subject to local regulatory authority approval.MAY 2003D626A001-CMRBOEING PROPRIETARY - Copyright (c) - Unpublished Work - See title page for details Page 9.0-148737-600/700/700C/800/900/900ER MAINTENANCE PLANNING DATAEXCEPTIONAL SHORT-TERM EXTENSIONSSince CMR intervals are based on statistical averages and reliability rates, an exceptional short-term extension of 10% for each CMR listed in thisdocument may be made without jeopardizing safety. The local regulatory authority (e.g. a Principle Maintenance Inspector) mustconcur with anyexceptional short-term extensions before they take place using procedures established with the local regulatory authority in the operators’ manuals. The“exceptional short-term extension” process is applicable to CMRintervals. It should not be confused with the operator’s “short-term escalation” programfor normal maintenance tasks described in the operators’manuals and in the FlightStandards Handbook 8300.10.The Seattle FAA ACO has accepted that these exceptional short-term extensions may be granted without consultation with that office:1. The term “exceptional short-term extension” is defined as an increase in a CMR interval that may be needed to cover an uncontrollable or unexpectedsituation. All CMRs listed in thisdocument have been approved with an exceptional short-term extension of 10%.2. Repeated use of extensions, either on the same airplane or on similar airplanes in an operator’s fleet, should not be used asa substitute for goodmanagement practices. Exceptionalshort-term extensions must not be used for fleet CMR escalation.After a CMR has experienced an exceptionalshort-term extension, the CMR interval will revert back toits interval listed in this document. The Seattle FAAACO must approve, prior to its use, any desired extension not explicitly listed above.This exceptional short-term extension listed above applies to airlines that fall under the United StatesFAA jurisdiction only.Operators who are not underthe U.S. FAA jurisdiction should obtain interval extension approvals from their local regulatory agency.FEB 2008737-600/700/700C/800/900/900ER MAINTENANCE PLANNING DATAD626A001-CMRBOEING PROPRIETARY - Copyright (c) - Unpublished Work - See title page for details Page 9.0-149POST-CERTIFICATION CHANGES TO CMRsAny post-certification changes to CMRs should be reviewed by the 737-600/700/700C/800/900/900ER CMCC and approved by the Seattle FAA ACO:1. Since the purpose of a CMR is to limit the exposure time to agiven significant latent failure as part of an engineering analysis of overall systemreliability, instances of a CMR task repeatedly finding that nofailure has occurred may not besufficient justification for deleting the task or increasing thetime between repetitive performances of the CMR task. In general, * CMRs are not good candidates for escalation under an operator’s reliabilityprogram. A * CMR task change or interval escalation can only bemade if world fleet service experience indicates that certain assumptions regardingcomponent failure rates made early during the engineering analysiswere overly conservative, and a re-calculation of system reliability with revisedfailure rates of certain components reveals that the * CMR task or interval may be changed.2. The introduction of a new CMR or any change to an existing CMR should be reviewed by the same process used during initial certification. It isimportant that operators be afforded the same opportunity to participate that they received during the original certification of the airplane, in order toallow the operators to manage their own maintenance programs.3. In the event that later data provide sufficient basis for relaxation of a CMR (less restrictive actions to be required), thechange may be documented by anFAA ACO approved change to this CMR document.4. If the requirements of an existing CMR must be increased (more restrictive actions to be performed), it will be implemented by a change to this CMRdocument and enforced by an FAA Airworthiness Directive (AD).5. After initial aircraft certification, the only basis for adding a new CMR is inassociation with the certification of designchanges.6. A new CMR created as part of a design change should be partof the approved data for that change and added to this CMR document.In the event that a CMR is revised, Boeing will document it by preparing a revision to this document that will be approved by the Seattle FAA ACO. Thisrevision will then be forwarded to all 737-600/700/700C/800/900/900ER operators and theSeattle FAA ACO offices.JUN 2011D626A001-CMRBOEING PROPRIETARY - Copyright (c) - Unpublished Work - See title page for details Page 9.0-150737-600/700/700C/800/900/900ER MAINTENANCE PLANNING DATATYPE KASTEXAMPLE ILLUSTRATING FORMAT12000 HRSSYSTEM.Operationally check CENTER HYDRAULIC ISOLATION29-13029-CMR-02* OPALL ALL737-600/700/700C/800/900/900ERITEMCMRNUMBERITEMMRBRELATEDNUMBERENGAPLTASK DESCRIPTIONAPPLICABILITYINTERVALCMRCERTIFICATION MAINTENANCE REQUIREMENTS

REPORTING UNCONTROLLABLE HIGH THRUST FAILURE CONDITIONSTitle 14 Code of Federal Regulations sections 121.703 and 135.415 state that “each certificate holder shall report any failure,malfunction or defect in anaircraft, system, component, or powerplant that occurs or is detected at any time if, in its opinion, that failure, malfunction, or defect has endangered ormay endanger the safe operation of an aircraft.” Section 125.409 also requires reporting offailures, malfunctions, or defects. In many cases a reportablefailure or malfunction will be obvious, but thereare some failure modes related to uncontrolled high thrust that are reportable but may not be obvious. Thefollowing information is provided, as required by FAA ExemptionNo. 7968 to assist the operators in identifying reportable malfunctions related touncontrolled high thrust.The FAA has concluded that the loss of capability to control thrust dueto a failure of the enginethrust control system may endanger the aircraft. Thisincludes any malfunctions having one ormore of the following characteristics.• Auto-acceleration or uncommanded thrust change to higher power• Stuck thrust lever above idle power• Inability to reduce thrustAlthough some of these incidents may not appear to be safety related, documenting the events is important to ensure the presentlevel of safety ismaintained and/or to identify failureconditions that must be corrected.When filing a report of such an event with the FAA, the operatoris requested to include in the description of the event one ormore of the followingphrases:• “thrust control”• “no response to thrust lever’• “auto-acceleration’• “uncontrolled high thrust”FEB 2011D626A001-CMRBOEING PROPRIETARY - Copyright (c) - Unpublished Work - See title page for details Page 9.0-160737-600/700/700C/800/900/900ER MAINTENANCE PLANNING DATAIn addition, the following information should be included in the report:• Event description• Flight crew action• Maintenance action• List of affected or removed componentsReports should be submitted to the local representative of theFAA Administrator that handles the appropriate reporting responsibility for 121.703, 125.409,and 135.415.
